Patented Aug. 19, 1941 UNITED STATES PATENT OFFICE BOTTLENECK John Kreuach, Detroit, Mich. Application April 7, 1941, Serial N0. 387,231

- 3 Claims. (01. 215-8) The purpose of the invention is to provide a bottle in which a, sea1 or a, pluraitynf seals placed over the outlet may nct be broken without leaving indications of its having been tampered with and in which a, sea1 once brokz'an cannotfibe replaced Without bre:aking the neck of the bottle.

Another object of my invention is 120 provide a device of this character of simple construction and employing a combination of parts which are easy I;o make and easy to fit together.

A further purpose of my invention is to provide a bottle neck of the kind described anal which does noi ca1l forany special means of closure nor for any special means of removing said clo sure of whatever type same may bei i I shal1 now describe my invention in detail with reference 130 the accompanying drawing, in

Fig. 1 shows a longitudinal sectional viaw through I;he neck of the bott1e, said neck forming one part of my invention.

Fig. 2 is a longitudinal section through the neck of the bottle including my improvements therein.

Fig. 3 is a section taken on 1ine 3-3 of Fig. 2.

Fig. 4 is a section taken on line 4-4 of Fig. 2.

Fig. 5 is a section haken on 1ine 5 -5 of Fig. 2.

Fig. 6 is a. section taken on line 65 of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

The neck of the bott.le comprising my improvement isindicated Ioy numeral I0 am! is shown in detail in Fig. 1. I1; will be noted that this neck I0 is provided ab some distance fro-m its mouth IIa with an inner orifice or neck II. neck may be provided with an external thread I4 to receive a threaded cap I3, 01 it may be otherwise made suitable to receive an appropriate closure. Said neck I0 contains ab its upper end, close to the mouth I Ia, two diametrically opposed slots I2 on the inner wall of seid neck I0, as shown, although obviously I:he number of said slots may be more than two. When it is intended I:o close the bottle, this may be done as above sta.ted by means of a crown cap I3 whinh is fitted over the inner neck II. The cap m-ay be provided at the top with a depressed circular center I5 3.11d a cross S101; I6 120 afford a hold for a, 1:001 employed for I7he purpose of unscrewing the cap. The line of demarc ation of said circular center I5 is partly auf; so that when desired I:he center may be pushed inwardly by a suitable too1 say, a screw-driver, a rod or some si-mil-ar means. If preferred the bott1e may be closed by means of an ordinary cork I8.

The inner In order 1:0 forestall tampering with the Contenhs of I;he bottle, it is cusoomary to plac6 a seal over the closure in the mouth of the h0iztile and such a seal is indicated here by numeral II. In Fig 1 it isshown ppliedover a cork I8 in the neck II, whi1'e in Eig. 2 ii: is shown applied over a crown cap I3. The seal may be nia.de of paper 011 some other suiipable material. I

Up t0 this time I have been describi'ng ihe bottle and the means to elose same said neck of the bottle being as shown in Fig. 1. II: is obvious that were the.mouth Ila 0f the bottle neck left open, this would make the seal readily accessible anal thus make it possible to tamper with same. In order to forestall, this, I have devised ap1ug 20 which fits into che open neck ofsaidbottle through said mouth IIa, in such amanner that I:he plug prevents tampering with the seal and yet does not preverit the bottle from being emptied when desired. Saidplug 20 (30H- sists 0f asubstahtially hollow cylinder sep'an2ited by apartition 2I into two chambers, a domed chamber 22 open at one end, and a. chamber 23. A central opening 28 and a plurality of opem'ngs 29 surrounding same cgnnects the -two chambers. The upper cha-mber opens into outlet 24, which is of a diameter smaller than that of either of the chambers. The plug contains at least two pins 25, which are urged outwardly by coiled springs 26. When the plug is inserted inoo the neck I0 of the bottle, these pins 25 urged by springs 26, slip into slots I2 making it impossible t0 withdraw plug 20 from the neck I0 of the bott1e. In order 1:0 secure a, liquid-tight contact between the neck I0 and the plug 20, I have banded the plug with two cork gaskets 2'I, one in the plane of the partition 2I and the other one c1ose to the neck of the bott1e, above the 1evel of pins 25.

In order to complete the description of the plug, I want to add that projecting from the dome of said partition 2I into the lower cha.mber 22 :are two or more sharp pointed prongs 30. Another seal 3 I, also made of paper or some other suitable material, is placed in the 1ower chamber in a spaced relation to sea1 I'I, which is placed right over the closure of the inner neck I I. The unter neck Ila may be suitably closed by a cap or cork, but I am 11013 describing same as this is no part of my invention.

I shall now describe the use of my invention: When the seals are in place and the plug has been inserted into neck I0 so that it is held thereby by means of pins 25, it is not possible to pour out the contents of the bott1e without breaking the seals.

Assurning that the inner neck H is closed by a cork, a corkscrew may be used for the purpose of withdrawing it from said neck l l, in which case the corkscrew would be extended towards the cork through the outlet 24 and through the centra1 opening 28 in partition 2'I. In order to screw in said corkscrew into cork closure I8, both seals 31 and IT would be broken. Then when a hold upon the cork had been secured, it would be possible 110 pull out the cork so that its top wouhi reach prongs 30. The prongs would. cut into the body of the cork and prevent same from being rotated while the corkscrew was being Withdrawn by rotation of the shank thereof. Otherwise, if it were not for the prongs, the rotation of the corkscrew would also impart a rotary movement to the cork so that withdrawal of the corkscrew would not be possible without sufi1cient force to tear the texture of the cork. Because the cork in its withdrawn position wou1cl partly block the central passage 28, the liquid contained in the bottle wou1d be able to flow out through passages 29 into -chamber 23 and then through mouth 24. In case 1Jhe inner neck is closed by a cap, same could be unscrewed by inserting a screwdriver into thecross slot I6 and rotating the cap, 01 the central portion 15 partly cut could be pressed in on the line of partly cut demarcation of said central portion. But again in order to reach the contents of th-e bottle, seals I1 and 3I would have to be broken.

Once the bottle has been opened, as above described, it may again be closed Joy means of a cork stoppen cap or other means Which may be applied to the mouth 24.

It will .be Seen that soxne slight changes may be introduced in this construction without departing from the spirit of my invention. What I, therefore, wish to claim is as follows:

1. In combination a cylindrical bottle neck including an inner orifice centrally located therein and adapted 1:0 be closed and sealed, and a hollow cylindrical plug adaped to fit into said neck and. divided by a transverse partition into a lower chamber extend above said orifice, and an upper chamber leading to an outlet, said partition being provided with a plurality of openings connecting said chamoers, projecting means on the plug, and corresponding slots on the inner surface of the neck to prevent the plug frorn being removed therefrom.

2. In combination a cylindrical bott1e neck having slots on the inner surface thereof and including an axially located orifice spaced from the outer end of said neck, a hollow cylindrical plug adapted to fit into said neck, and comprising spring actuated radial projections to s1ip into said slots, a transverse partition 170 divide said p1ug into a 1ower chamber above said orifice, and an outer chamber leading an outlet, said partition being provided With a plurality of openings, including one located centrally, and further provided with sharp prongs projecting downwardly into the lower chamber, a closure for the orifice, and a fragile sealing means over said closure.

3. In combination a, cylindrical bottle neck provided with slots on its inner surface, and including an axially disposed orifice Within said neck, but spaced from the outer end thereof, closure means for said orifice and. fragile sea1 means 0ver said. closure means, a h0110w cylindrical ph'1g adapted 130 snugly fit into the neck, radial projecting pins 011 said p1ug 110 fit into said. slots, annular cork gaskets on said plug to insure liquid-tight contact with the inner surface of said cylinder, said plug containing midway' between its ends a partition perforated to afford passage for liquids, and provided with sharp prongs on its lower surface 130 check lshe1ot2nc movement 015 the closure means, when said closure means has been moved out of engagement with the orifice.
